When you start shopping around for a projector screen, you might get puzzled with the way too many varieties available in the market. While each variety seem to be unique in its own way, you can achieve the best results only after you have zeroed in on a projector screen that co-ordinates with the projector concerned. That being said, you should understand that special projector screen is classified on the basis of the light reflecting materials of the screen. Now have a check on the different types of screens that you can find in the market.
They are designed to reflect light all over its surroundings. So even if people sit scattered all over a room, they can experience the same quality of picture. The projector is designed to light uniformly, so the images are shown with same brightness from any angle that comes within the screen’s projection cone. Nevertheless, you can see the overall brightness getting reduced, as the light is spreading out in all directions. You will see that most of the packaging cartons of diffused screens read that the unit has a ‘gain of 1’. Gain, here refers to the ability to reflect on any projection surface or screen. It is basically a ratio of light, which is reflected from screen, as compared to light that a standard magnesium dioxide (white) screen reflects. So having a gain of 1 means it will reflect equal amount of light to that of a white screen. Diffused projectors are ideal for business and conference purpose and makes for an excellent unit for rental. You can also consider them for educational purpose, theaters, home cinema and entertainment, 3 D projections, as well as for video conferences.
You can find them helpful when you have plenty of ambient light where the projection will be used. Since reflective screens work like mirrors, they are best avoided for rear end projectors. They typically have a gain of 2. This special projector screen works best for ceiling mounted projectors, since they can reflect lights on narrow viewing angles. This works good when you need to deliver a presentation in front of some 20-30 people.
When you are using your projector in a setting with a naturally well-lit area, then these screens are made for you. Designed to reflect the available ambient light back to its source, the retro-reflective screens are quite high on projector gain. However, they might not give you the best results, when paired with ceiling mounted projectors. You would rather use them with a small, table mounted unit.
Rear Projection Screens
Finally, if you have a back projection projector, then so safe with this special projector screen and enjoy the liberty of using them under any condition. You can be rest assured that the image quality is not going to be affected by any means. This is because; the source of the image comes from the rear of the screen. Again, since they typically come with a high gain of 6, rear projector screens deliver fantastic performance even under extremely bright condition. You might find them a little more expensive than their front end peers, though. In keeping in that, you can consider using it typically for professional usage, especially when you have a presentation in front of a huge gathering.
